Add a "System.exit( 0 );" to the end of your main() method.

When main() ends, all that means is that that thread has finished.  If 
your process has other (non-daemon) threads running, it will continue to 
run until they finish, also.  Unless you hard-terminate the process.

If you're trying to prove a point, you could add a random sleep in 
before calling System.exit(0), then you'd see nondeterminism at work and 
could be happy that it was doing what you wanted.

On the other hand, if what you're after (and I can't tell from your 
email, sorry), is that the "Hello World"'s keep printing even after the 
java process has exited, you need a Runtime.exec() or fork(), not a 
pthread_create().  I suspect you know this, but thought I'd throw it in 
just in case.
